From sophisticated coding agents and LLM-driven applications to innovative games and developer tools, the entrepreneurial spirit of Hacker News shines through. This monthly staple offers a fascinating glimpse into current trends and the ongoing quest to solve problems, big and small, often with the enthusiastic assistance of AI.
The Lowdown
The March 2026 edition of "Ask HN: What Are You Working On?" once again served as a dynamic showcase for the Hacker News community's diverse and ingenious projects. This recurring thread is a beloved tradition, offering a platform for developers, tinkerers, and entrepreneurs to share their progress, solicit feedback, and find inspiration. This month's contributions highlighted a significant trend towards leveraging artificial intelligence, with many projects directly integrating or building upon large language models and agentic workflows.
Key themes emerging from the thread include:
- AI-Powered Innovation: A substantial portion of projects involved AI, from building intelligent coding agents and automated content generators to specialized LLM-powered applications for finance, legal, and educational domains. The term "vibe coding"—an exploratory, LLM-assisted development style—was frequently mentioned.
- Games & Creative Tools: Many developers shared progress on games ranging from retro-inspired city builders and unique puzzle games to MMORPGs and MUD-style simulations featuring AI-controlled characters. Creative applications extended to music livecoding and 3D modeling for crafting.
- Developer Productivity & Infrastructure: Enhancing developer workflows remains a core focus, with projects unveiling new programming languages, alternative build systems, niche databases, performance-optimized utilities like HTML-to-PDF converters, and robust infrastructure solutions.
- Niche Problem-Solving & Personal Utilities: The thread also featured a variety of highly specialized tools tackling unique problems, such as bespoke personal finance managers, accessible color palette editors, car immobilizers, and systems for managing meeting fatigue.
Overall, the thread underscored a strong current of practical innovation, often driven by personal need or curiosity. The collaborative and supportive nature of the Hacker News community was evident in the feedback and encouragement shared among participants.
The Gossip
The AI Ascent: Agentic Advances & App Automation
A predominant theme was the integration of AI, particularly large language models and coding agents, into a wide array of projects. Many shared tools for automating development tasks, like AI-powered test frameworks or deployment orchestrators, often enabled by 'vibe coding'. Others built consumer-facing applications that leveraged LLMs for complex functions, such as NSFW content filtering, legal document processing, personalized novel generation, or language learning support. Discussions also touched upon the challenges and opportunities in building robust, secure, and cost-effective AI solutions.
Gaming & Creative Codecraft: Pixel to Physical
This thread showcased a vibrant array of games and creative coding projects. Enthusiasts presented everything from nostalgic city-builders with modern twists and award-winning daily puzzle games, to idle MMORPGs and unique MUD-style simulations powered by LLMs. Beyond digital games, individuals shared endeavors like 3D printing custom parts for sentimental items, demonstrating a fusion of coding skills with tangible creative pursuits.
Developer Utilities & Infrastructure Innovations
A significant portion of the shared projects focused on enhancing developer workflows and underlying infrastructure. This included the development of new programming languages, specialized build tools, high-performance utilities like a pure Go HTML-to-PDF converter, and innovative database solutions. Several contributors detailed efforts to build semantic search engines, agent orchestrators, and system-level tools to improve efficiency, performance, and security in development environments.
Niche Problem-Solving & Personal Productivity
Many participants presented highly specialized tools and applications, often born from personal frustrations or unique needs. Examples included micro-SaaS ventures for tax optimization and emergency communication, an app to filter meeting distractions, and DIY hardware solutions like a custom car immobilizer. These projects underscore a common Hacker News ethos: building solutions for specific, often overlooked, problems to enhance productivity or simplify life.
